(e)  RHJI and the Principal Company Shareholders each shall notify Argon promptly of any acquisition or Transfer of Shares by it or any of its Affiliates and Argon shall notify the other parties to this Agreement promptly of such acquisition or Transfer, in each case with information with respect thereto sufficient to permit the parties to this Agreement to determine the aggregate number of Shares held by each party hereto and its respective Affiliates in order to comply with their respective reporting and filing requirements regarding share ownership under Japanese law and the rules and regulations of the TSE.

with respect to any single event or series of related events and all such suspensions shall not exceed 180 days in any twelve-month period (the “Deferral Period”). Argon shall promptly give the Principal Company Shareholders written notice of any such suspension containing the approximate length of the anticipated delay, and Argon shall notify the Principal Company Shareholders upon the termination of the Deferral Period.

(b)                                 Termination or expiration of this Agreement shall not relieve the parties of any obligation accruing prior to such termination or expiration and shall be without prejudice to the rights and remedies of any party with respect to the antecedent breach of any of the provisions of this Agreement. The provisions of Sections 18, 20 and 24 shall survive any termination hereof.

(b)                                 Argon recognizes that a Principal Company Shareholder may have one or more limited partners that require certain information and consultation rights from Argon in order for such limited partner to continue to qualify as a “venture capital operating company” (“VCOC”), as that term is commonly referred to under ERISA (as

17

defined in the Parent Stock Purchase Agreement). Argon hereby agrees to provide promptly any such requesting limited partner of a Principal Company Shareholder (which limited partner can substantiate a legitimate requirement to Argon’s reasonable satisfaction) with a VCOC letter substantially consistent with similar VCOC letters previously issued by Argon to HIP and CSFB (but excluding any right to have observation rights at the Board of Directors).

11.                                 Further Assurances. Each Shareholder shall endeavor to take or cause to be taken all actions, and to do or cause to be done all other things, necessary, proper or advisable in order to fulfill and perform its obligations in respect of this Agreement. From time to time, each Shareholder shall, in cooperation with the other parties hereto, as appropriate, execute and deliver, or cause to be executed and delivered, such additional documents and instruments, and take such other actions as may be reasonably requested by the other party or parties to render effective or otherwise carry out the intent and purposes of this Agreement.

12.                                 Amendments. This Agreement may be amended only by a written instrument executed by RHJI and the Principal Company Shareholders holding a majority of all the Shares then held by all Principal Company Shareholders; provided, however, notwithstanding anything to the contrary in this Agreement, no amendment or change to (i) any representation and warranty in this agreement that is adverse to the Principal Company Shareholders may be made without the approval of each Principal Company Shareholder, (ii) the existing liabilities or obligations of any Principal Company Shareholder under this Agreement that is adverse to such Principal Company Shareholder may be made without the approval of such Principal Company Shareholder or (iii) provide any additional benefit or right to HIP or RHJI under this Agreement (other than as provided as of the date hereof) may be made without the approval of each Principal Company Shareholder.

13.                                 Binding Agreement. This Agreement and the rights and duties of the parties hereto shall be binding upon and shall inure to the benefit of the parties hereto and their respective executors, administrators, heirs, successors and permitted assigns; provided that such rights and duties may not be assigned by any party hereto (and any such assignment shall be void) except that any Permitted Transferee acquiring any Shares shall become a “Shareholder” in accordance with Section 4(a).

14.                                 Conflicts - Articles. Each of the Shareholders shall take all action necessary, including but not limited to the voting of their Shares, to ensure that the Articles of Argon and the Articles and by-laws or other governing documents of Argon’s Subsidiaries are consistent with, and do not conflict with, the terms of this Agreement and undertake to amend the Articles to incorporate some or all of the provisions of this Agreement, to the extent reasonably determined by RHJI. The Shareholders undertake to sign any other document reasonably deemed necessary by Argon to give effect to this Agreement. To the extent legally permissible, in the case of conflict between the Shareholders, the provisions of this Agreement shall take precedence over the Articles.

15.                                 Entire Agreement. This Agreement constitutes the entire agreement and understanding among the parties hereto with respect to the matters

referred to herein (other than with respect to a certain agreement between HIP and CSFB regarding the exercise of their rights as Principal Company Shareholders under this Agreement) and supersedes all prior agreements and understandings (including the Original Agreement) among the parties hereto with respect to the matters referred to herein.

16.                                 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the agreement contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the agreement contemplated hereby be governed as originally contemplated to the fullest extent possible.

17.                                 Benefits of Agreement; Third-Party Rights.

18.                                 Governing Law. This Agreement and all actions contemplated hereby shall be governed by and construed and enforced in accordance with the laws of Japan.

19.                                 No Waiver of Rights. No failure or delay on the part of any party in the exercise of any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power or right preclude any other or further exercise thereof or of any other right or power. The waiver by any party or parties hereto of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any other or subsequent breach hereunder. All rights and remedies existing under this Agreement are cumulative and are not exclusive of any rights or remedies otherwise available.

20.                                 Submission to Jurisdiction. Any and all suits, legal actions or proceedings arising out of this Agreement shall be brought either in the courts of Japan or in U.S. Federal court located in the Southern District of New York, and each party hereto hereby submits to and accepts the exclusive jurisdiction of such courts for the purpose of such suits, legal actions or proceedings. To the fullest extent permitted by law, each party hereto hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any such suit, legal action or proceeding in any such court and hereby further waives any claim that any suit, legal action or proceeding brought in any such court has been brought in an inconvenient forum.

19

21.                                 Specific Performance. The parties hereby declare that irreparable damage would occur as a result of the failure of any party hereto to perform any of its obligations under this Agreement in accordance with the specific terms hereof. Therefore, all parties hereto shall have the right to specific performance of the obligations of the other parties under this Agreement, and if any party hereto shall institute any action or proceeding to enforce the provisions hereof, any Person against whom such action or proceeding is brought hereby waives the claim or defense therein that such party has or have an adequate remedy by the payment of a financial compensation. The right to specific performance should be in addition to any other remedy to which a party hereto may be entitled.

22.                                 Costs. Save as otherwise provided in this Agreement or in the Stock Purchase Agreement, the parties shall be responsible for and shall bear their own costs (including those of their respective external advisors) in connection with this Agreement and their participation in Argon.

Each party hereto may from time to time change its address for notices under this Section 23 by giving at least five Business Days’ notice of such changed address to the other parties hereto.

24.                                 Confidentiality. Each party undertakes to take all necessary measures to keep the contents of this Agreement strictly confidential and not to disclose it to third parties, provided that each Shareholder shall be permitted to disclose the contents of this Agreement if required or advisable as a matter of applicable law (including rules of the stock exchange on which any shares of Argon are listed) or to any entity which it believes in good faith to be seriously considering a significant investment in or loan to Argon so long as such entity has executed a confidentiality agreement and, with respect to any disclosure by a Principal Company Shareholder or Transferee thereof, either (i) Argon reasonably determines that such entity will be able to meet its obligations under such confidentiality agreement or (ii) such Principal Company Shareholder agrees to be liable for the obligations of such entity under such confidentiality agreement. Each Shareholder undertakes to take all necessary measures to keep any confidential information of Argon and its Subsidiaries strictly confidential and not to disclose it to third parties without the consent of Argon. The foregoing restrictions on disclosure shall not apply to information that (a) can be demonstrated to have already been known to the receiving party (the “Receiving Party”), without restriction as to confidentiality or use, prior to disclosure of same by Argon; (b) is received from a third party without restriction as to confidentiality or use, by a third party lawfully entitled to possession of such information and who does not violate any contractual, legal or fiduciary obligation, direct or indirect, to keep such information confidential; (c) was in or becomes part of the public domain through no fault of the Receiving Party; (d) the Receiving Party is legally compelled to disclose; (e) is disclosed as required to enforce this Agreement; or (f) is to be disclosed to any prospective Transferee; provided that (i) the prospective Transfer must be permitted under this Agreement, (ii) the prospective Transferee enters into a written confidentiality agreement with Argon reasonably satisfactory to Argon and (iii) either (A) Argon approves the prospective Transferee which enters into such confidentiality agreement, which approval shall not be unreasonably withheld (the poor creditworthiness and/or negative business reputation of such prospective Transferee being a reasonable basis for Argon to refuse its approval) or (B) the Receiving Party agrees to be liable for such prospective Transferee’s obligations under such confidentiality agreement. In the event that the Receiving Party becomes legally compelled (by deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar process or otherwise) to disclose any of the information, the Receiving Party shall provide Argon with prompt prior written notice of such disclosure requirement (which shall include a copy of any applicable subpoena or order) so that Argon may seek a protective order or other appropriate remedy and/or waive compliance with the terms of this Section 24. In the event that such protective order or other remedy is not obtained, or that Argon waives compliance with the provisions hereof, the Receiving Party agrees to furnish only that portion of the information which the Receiving Party is advised by written opinion of counsel is legally required and to exercise best efforts to obtain assurance that confidential treatment will be accorded such

21

information. Each party further agrees not to make any public announcement or press release relating to this Agreement without the prior written consent of the other parties hereto and without an agreement on the content of such disclosure.

25.                                 Definitions Generally. Definitions in this Agreement apply equally to both the singular and plural forms of the defined terms. The words “include” and “including” shall be deemed to be followed by the phrase “without limitation” when such phrase does not otherwise appear. The terms “herein”, “hereof” and “hereunder” and other words of similar import refer to this Agreement as a whole and not to any particular section, paragraph or subdivision. The section titles appear as a matter of convenience only and shall not affect the interpretation of this Agreement. All section, paragraph or clause references not attributed to a particular document shall be references to such parts of this Agreement.

26.                                 English Version Authoritative. The Shareholders agree that any dispute shall be resolved solely based on the English language version of the definitive documentation.
